Feeling like a failure

Well I failed the shit out of my 1-hr glucose test. Also got diagnosed with gestational hypertension at today’s appointment and was told I might need additional ultrasounds to monitor baby’s growth. I feel like I am failing my son already and he isn’t even here yet. I was overweight before pregnancy but had no health problems but now I feel like my less than ideal health choices before and during pregnancy are catching up to me and could affect my baby. My husband says I’m overreacting and maybe he’s right but I’m so upset
